P-12 STEREO POWER AMPLIFIER AND HEADPHONE DRIVER OWNERS

MANUAL

Congratulations on the purchase of the US Audio P-12 power amplifier. The P-12 is a

stereo 12 Watt amplifier capable of producing moderate listening levels through speakers

and headphones.

Front Panel

1.

Channel and 2 volume controls

These knobs vary the amplifier output level.

2.

Channel and 2 Clip LEDs

These LEDs will light when the P-12 amplifier output is approximately 3dB below

clipping. (You will hear audible distortion if the amplifier is run at clipping.)

3.

Headphone Phones/Speaker switch

When this switch is in the speaker position (out) the speaker out terminals on the back

panel are active while the headphone jack on the front panel and the XLR headphone

jack on the back panel are off. When this switch is in the headphone position (in), the

headphone jack on the front panel and the XLR connector on the back panel are active

and the speaker terminals are off.

4.

Phones jack

This is a quarter inch tip ring sleeve headphone jack. The unit will operate properly with

8 Ohm to 600 Ohm headphone impedances.

Rear Panel

1.

CH1 and CH2 Input Jacks

These jacks are quarter inch, unbalanced, audio inputs.

2.

Headphone Out XLR

This headphone output XLR connector is active when the Headphone/Speaker switch is in

the headphone position. When used with the US Audio Headphone Satellite boxes and

standard microphone cables, the P-12 can drive multiple sets of headphones, with

individual volume controls.

3.

CH1 and CH2 Speaker Outputs

These speaker terminals are active when the Headphone switch on the front panel is in

the speaker position. The P-12 will drive impedances of 4 Ohms or greater.
